One more question for today...
I have a mail system behind a firewall (running NAT), with a whole in the firewall to let mail through. But when I send mail out the host name of the mail server does not match the reverse lookup of the ip the receiving system thinks the mail is from (it sees the firewall IP).
This causes the recieving host to think the mail might be forged.
What do I set in the sendmail.mc to to force sendmail to say it's form the firewalls hostname, so recieving hosts think it's all good?
